FST 2.12发布,Java快速序列化库

　　FST 2.12 发布了，改进记录包括：

• did some optimization to get 2.x performance closer to 1.x

• added (optional) off heap configuration using unsafe to read/write values

• added simple api (see DefaultCoder) to directly serialize from/to byte arrays without the need for streams

• added possibility to directly serialize from/to offheap memory (long adr) zero copy (see OffHeapCoder, OnHeapCoder).

• added Long2Object Offheap hashmap

• fixed bug in offheap map

　　FST fast-serialization 是重新实现的 Java 快速对象序列化的开发包。序列化速度更快（2-10倍）、体积更小，而且兼容 JDK 原生的序列化。要求 JDK 1.7 支持。
